  "map_content": "Twenty years ago this month, I stood before a room at Google and presented work on deep learning networks.\r\nFor ninety minutes the questions came, and for ninety minutes I answered them.\r\nThe objection, when it finally arrived, was wonderfully mundane.\r\n\"It requires too much compute.\"\r\n\"Perceptrons are too slow.\"\r\nI suggested something unfashionable at the time. I suggested looking forward.\r\nMoore's Law was hardly a secret. Computing power was increasing relentlessly. If we started then, if we built for where hardware would be rather than where it happened to be that afternoon, we would arrive ahead of the curve.\r\nThe response was largely the sort of practical wisdom that ages badly. The future was judged by the limitations of the present. A common habit among intelligent people.\r\nToday we live in a world intoxicated by Large Language Models.\r\nEvery newspaper speaks of them. Every boardroom discusses them. Every investor discovers them with the enthusiasm of a tourist finding Paris.\r\nYet the amusing thing is that LLMs did not appear because somebody suddenly discovered neural networks. They appeared because computation finally caught up with ideas that many had dismissed as computationally expensive curiosities.\r\nThe mathematics did not perform a miracle.\r\nThe silicon improved.\r\nWhat was once \"too much compute\" became routine.\r\nWhat was once \"too slow\" became infrastructure.\r\nWhat was once dismissed as impractical became one of the largest technological revolutions of the century.\r\nThere is a peculiar vanity in assuming that the limits of today's hardware are the limits of tomorrow's civilisation. It is rather like refusing to build a cathedral because one happens to be standing in a quarry.\r\nThe future rarely arrives by inventing entirely new ideas.\r\nMore often, it arrives by waiting for old ideas to become affordable.\r\nAnd so here we are, surrounded by LLMs, watching the world celebrate what many once rejected, not because it was wrong, but because it was early.\r\nThe difference between a visionary and a sceptic is often nothing more than ten years of semiconductor manufacturing.\r\nOr twenty.",
